Abstract

Attribute reduction of rough set is a very important research topic. The shortcoming of Reference [8,9]’s method is got a superset of a true reduction sometimes, and the disadvantage of Reference [10]’s algorithm is could not get a right attribute reduction sometimes. To overcome the above shortcomings, a new heuristic attribute reduction method based on Boolean matrix is put forward. Finally, the method’s feasibility and validity are proved by examples.
